Some forms can jump from birds to mammals and on to humans.The strain causing concern is highly pathogenic and the disease it causes is currently called HPAI.Should one be concerned about contracting avian influenza?Avian influenza exists naturally within populations of wild birds and has been called fowl pest and fowl plague for the particularly decimating impacts that occur when these naturally occurring strains becomevirulent. There are many strains of avian influenza that occur in wild and domestic bird populations and in many of these do not cause illness for the birds they inhabit. Avian influenza is frequent within waterfowl andshorebirds and to a lesser extent gulls. Few bird viruses are able to infect humans. HPAI is primarily an animal disease and unless people come into direct sustained contact with infected birdsit is unlikely they will contract the disease. The H5N1 virus has demonstrated the ability to infect and produce a fatal illness in humans living under those circumstances. If the virus evolves the capacity for sustainedhumantohuman transmission it could spread quickly around the world.
